Assembling method for orthotropic steel bridge deck of all-welded steel truss girder
The invention discloses an assembling method of an all-welded steel truss orthotropic steel bridge deck slab, and relates to the technical field of bridge construction, the method comprises the following steps: arranging crossbeams of a current bridge deck slab mother section with a set length at intervals along a set direction, laying a bridge deck slab unit above the crossbeams with the set length, and suspending the end part of the bridge deck slab unit; crossbeams with the length of the suspended position of the bridge deck slab unit of the previous bridge deck slab mother section are arranged at intervals in the set direction, the crossbeams with the set length of the next bridge deck slab mother section are continuously arranged, the bridge deck slab unit of the previous bridge deck slab mother section is spliced with the crossbeams at the suspended position, and the next bridge deck slab unit is laid on the crossbeams of the next bridge deck slab mother section; and the step is repeated until installation of one bridge deck assembling section is completed. Transverse contraction generated by welding when the adjacent bridge deck units are laid is adapted through self-deformation of the end suspension sections, so that the transverse position precision of the longitudinal ribs of the bridge deck is guaranteed.
本发明公开了一种全焊钢桁梁正交异性钢桥面板的组拼方法，涉及桥梁施工技术领域，该方法包括以下步骤：沿设定方向间隔设置设定长度的当前桥面板母段的横梁，在该设定长度的横梁上方铺设桥面板单元，并使桥面板单元的端部悬空；沿设定方向间隔设置上一桥面板母段的桥面板单元悬空处长度的横梁，并继续设置设定长度的下一桥面板母段的横梁，将上一桥面板母段的桥面板单元与悬空位置的横梁拼接，并在下一桥面板母段的横梁上铺设下一桥面板单元，重复该步骤直至完成一个桥面组拼节段的安装。将相邻桥面板单元在铺设时由于焊接而产生的横向收缩通过端部悬空段的自变形来适应，以保证桥面板纵肋的横向位置精度。
